1. Executive Summary
The objective of the project was to create a circuit with an 8051 microcontroller that senses when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was

The project needed a circuit to pulse an infrared LED at 38 kHz, a circuit to receive the infrared signal, a seven segment LED display circuit, an auto-lighting circuit, and a programming circuit. The project also required code to be written to the 8051 microcontroller to combine all the smaller circuits into an operational system.
The 38 kHz generator, was major factor in getting the infrared receiver to operate correctly. A 555 timing chip was used to output a square wave at 38 kHz for an infrared LED. The generator needed to be completely isolated from the rest of the circuit because it was found that the infrared receiver’s output was similar to at a frequency of 38 kHz. The receiver needed to output a high until an object blocked the infrared signal when it would output a low.
* Seven Segment Display
One common requirement for many different digital devices is a visual numeric display. We've all seen seven-segment displays in a wide range of applications. Clocks, watches, digital instruments, and many household appliances already have such displays. A seven segment display is the most basic electronic display device that can display digits from 0-9. They find wide application in devices that display numeric information like digital clocks, radio, microwave ovens, electronic meters etc. The most common configuration has an array of eight LEDs arranged in a special pattern to display these digits.
They are laid out as a squared-off
This project has many applications and many future expansions and functions that can be added on. By having a variable floating DC power supply, 7Hz-6 KHz function generator, and oscilloscope with leads connecting to any circuit built, the comprehensive hands-on learning tool would be ideal for most DeVry students.
A concept for strain gauge based LED stumps was developed and tested using a prototype. The results of the prototype were encouraging. A concept for LED bails was also proposed. These concepts, once converted to embedded systems, could make the LED stumps much cheaper and
Introduction: In this assignment, I will explain the role of hardware and software components within a computer system. Furthermore, I will explain how they relate to digital graphics.I will also recommend suitable components for Cambridge Industrial Design. (P1)
| 1. Install, replace and repair lighting fixtures and electrical control and distribution equipment 2. Connect electrical power to sound and visual communication equipment 3. Test completation of circuits in electrical wiring, equipment and fixtures, using testing devices and ensure compatibility and safety of system
Infrared imaging is also used for military uses. This includes target acquisition, surveillance, night vision, homing and tracking (Infrared). This technology allows missiles and rockets to follow a target by tracking its heat. Night vision goggles and surveillance is used just as with the thermal imaging to detect things that give off heat and show them in a way that allows the human eye to see things that it normally could not.
1). Design the circuit for the given specifications. 2). Write the program code. 3).
a. Create a booklet which explain the function of hardware components and identify communication between components. The pages should include photographs and diagrams to illustrate the information you include. (P1)
An infrared system uses invisible light beams to carry sound from the cause to the personal receiver. The downfall is that the sound made must be in the line to properly work. It also requires many different types of attachments. The attachments may be connected to the personal receiver. The telecoil picks up sound from the receiver through the attachment.
The light emitting diodes (LEDs) are low energy, lighting devices with a long lifespan and low energy consumption. The LEDs use specialized power
Our intention of this project is to create and deliver a working prototype for our clients as a possible solution to the problem. Guidance and demonstration will be provided to the client for
Final Project Proposal - ECE 110 (ABC) Lab Akashdeep Deb and Sudeep Gummadi 1 Introduction and Problem Statement Electronics is a vast field and we, as a team, have just begun exploring the plethora of tasks that can be accomplished using some very simple but powerful electronics concepts. After having learnt a lot about electronics from the ECE 110 Lab section, we have decided that our final project is going to be a robot car which will be completely autonomous and would follow a line and will stop and move, when it would hear a clap. Furthermore, for additional aesthetics and functionality, we plan to add a few more sensors - heat (IR) sensors and a few LEDs which can sense the environment temperature and display the heat index using the LEDs. For this project, we have a few challenges to overcome: 1 No flex
The mote’s size makes energy management a key component. The circuit will contain circuits, a temperature sensor, and A/D converter, microprocessor, SRAM, communications circuits, and power control circuits. Sensors work together with the IC, which will operate from a power source integrated with the platform.
The display or the monitor allows for the data that has been processed by the CPU to be displayed as an image. Images can be displayed in black and white or in color depending on the make and model of the
This system includes simple three color traffic signal. A fixed time is allotted for each lane. The lights are automatically getting ON and OFF depending on the timer value changes. While using electrical sensors it will capture the availability of the vehicle and signals on each phase, depending on the signal the lights automatically switch ON and OFF. Before green light, yellow light flashes for few second, signifying to start your vehicle and be ready to go. For all the time red light is on, ordering each vehicle to stop. This method is efficient than manual controlling
RECEIVER SECTION:- This section is worked as a Flip-flop (Bistable). IC-3 is decade counter, its Pin No.14 is input and Pin No. 2 output. The output of frequency detector stage is used, via a flip-flop, to switch ‘ON’ or switch ‘OFF’ a LED alternately. The receiver uses infrared modules IR-signal from the transmitter is sensed by the sensor through and its output PIN 1 goes low and switched LED. IC-3 is worked on clock pulse which receives to infrared modules at Pin No. 14. Its output at Pin No 2 throughes high.
